CBET nr. 4140, issued on 2015, September 02, announces the discovery of a comet (magnitude ~18.5) by Eduardo Pimentel on Aug. 24.2 UT with a 0.45-m f/2.9 reflector of the SONEAR Observatory at Oliveira. Follow-up observations to confirm the object were obtained by C. Jacques, E. Pimentel, and J. Barros with the same telescope on Aug. 27.3 and31.3. The new comet has been designated P/2015 Q2 (PIMENTEL).

We performed follow-up measurements of this object, while it was still on the neocp. Stacking of 30 unfiltered exposures, 30 seconds each, obtained remotely on 2015, August 31.7 from Q62 (iTelescope network - Siding Spring) through a 0.50-m f/6.8 astrograph + CCD + f/4.5 focal reducer, shows that this object is a comet with a sharp central condensation surrounded by diffuse irregular coma 5" in diameter and a tail about 10" in PA 315
